| Abstract: | The deaerating device was designed based on the characteristics of laboratory. The factors affecting the deaerating process were analyzed. A series of calculation formulae for designing deaerating device were obtained by calculus method based on a certain mathematical model, including the foumula of calculating the deaerating speed of air bubbles, the thickness of solution film, resident time and the radius of distributing tubes, from which the length of umbrella can be calculated. The practice proved that the self-developed deaerating device can improve the deaerating efficiency greatly. |
